Two days after his murder, condolence are flooding social media. Friend, Chuck Claiborne, put his feelings down on Facebook. He describes Drumgole as a good listener.

"It really touched me and hurt me so much to know the way his life was taken away from his kids, but I truly know he's in heaven," said Claiborne. "When you run across a person this special, you get very emotional, knowing he was taken away from his kids and his wife just like that just doing what he had to do which was his job."

Police said 35-year-old Jamel Kingsbury stabbed him to death. He's still on the run.

At the mall on Monday, shoppers said the violence is alarming.

"It's hard for us to protect ourselves nowadays. We just have to be aware of our surroundings and walk with other people," said shopper Brittany Bolden.

"Malls are supposed to be fun and you shouldn't have to worry about being stabbed or anything harmful happening to you," said another shopper, Jovan Lawless.

Investigators believe Kingsbury is still in the area. If you know where he's hiding, call Prince William County police.
